. Ourinvention relates to improvements in that type of window fasteners in which a spring-actuated lever isarranged to engage a lug or post, upon theclosing of a lower window, or to be engaged by said post upon the closing of the associated upper window, whereby both windows are locked; and the objects of our invention are,first', to produce a strong, durable, and highly efficient, yet

comparatively simple and inexpensive, I device or appliance for automatically fastening windows when closed, vand an appliance which can be readily applied to practically any pair of upper and lower sliding windows; second, to provide the appliance with means for preventlng the introduction of an implementbetween said closed and fastened] windows for the purpose'of actuating the latch lever to 'unfa'sten the windows, said means comprising a plate which is retracted, when said lever is moved into inoperative position, in order not to interfere with the movement of the windows; third, to afford means for drawing the windows tightly together to prevent rattling and the passage of air therebetween or between their meet ing -rails; and, fourth. to improve both generally and specifically the construction of:

window. fasteners.

The ordinary window fastener having a spring actuated latch lever can not be em-' ployed to the best or even good advantage where the upper window in apair has ahorizontal partlng-rall or parting-ralls, because said lever normally extends 1nto the path of such parting-rails and interferes with the movement of the upper wlndow, and must be.

held with the thumb or finger out of the way while the parting-rails'are moved past said lever, or the latter is moved past the former, a more or less diflicult task, especially for a woman or child. Moreover, the operator is very liable to forget to hold the latch lever out of the way, and then the parting-rails are injured by more or less violent contact; with said lever. These objectional and un-] desirable liabili-ties are practically eliminat ed or avoided when our fastener is employed.

The means whereby is prevented theintroduction of a thin implement between the closed and fastened windows, when consistmg of a fixed lip,is not available, when horizontal parting-rails are present in the;

i upperwindow, if said lipis li-ablejto come into contact with said'jparting-rails.

7 Other objects and advant'ages' will appear. in the course of the following description- We attain the objects and jsecurethe ad vantages of our invention 7 p by the 'Ineans'illustrated- 1n the accompanying ,drawings,iin

Figurel is a 13 p Planof awindow fasteni errwhich embodies a practical formjof our inventlon, showing the guard plate retracted, and the latch lever disengaged from the post, and'disposed withits hook in extreme retracted position, and both incapable of contacting with any parting-rail; Fig. 2, is a slnnlariplan showing said'lever in 'engagement with said post, and saidfplate 'ad- 'vanced'; Fig.3, is another top plan illustrating the meeting-rails d'rawn'tightly together" and secured by means of the fastener; Fig.7

.4, is a right-hand side elevation of the fas-' '5, but disclosing the relative positions of said members when said plate is advanced, and, Fig. 7, is abottom plan of the fastener with the members disposed. substantially, as in'Fig- Similar reference characters designate-j similar parts through the several views.

In each of the first three views appear" if fragmentary portions of the meeting-rail; of a lower window sash, at 1, the-.meetingrail of an upper window sash, at2, and glass in the upper sash, atf3, said glass being in section. In Fig. {Lin addition to the afore said parts andmember's, which here arein section, appear one of the side-rails of the, lower sash, at 4, the glass therein,at 5, and one of the side rails of the'upper sash, at 6, said glass being in section. Putty for the two pieces off glass 3 and 5: is represented at-H'Z',

;These parts and members are merely typical cated. withthe back edge thereof flush with the back side/of said meeting-rail. The base 12 15 mounted on the meeting-rail 2 and secured to said meeting-rail by neans of two other screws 15, saidbase being located with its front edge flush with the front side of the meeting-rail.

In shape and size the bases 8 and 12 are generally similar, "and "said bases are relativelyarranged with. their corresponding ends in the same. vertical planes:-

, The post 13 has a head 16 which is generally conical in shape, but slabbed otl'on thc frontside. The post 13 is thus provided with an under-cut portion to receive between the same and thetop of the base/.12 a. hook 17 plane. spring at one end of the lever or latch 10. The'post 13 is located in the transverse center of the base 12, with the flat side of the head 16 ap proximately in the same plane with the front edge of said' base. I

hefriction plate 1 1 is ,locatedon top of the base 12 behind thepost 13, and has one end secured to said 'baseby means of arivet 18, said plate here being inQthe form of a plate spring slightly elevated intermediate of its ends. V

The pivot 11 is locatedapproximately in the center of the base 8, and passes down through the latchlO and the top of said base,

including a rectangular lug 19 on said top, to headed over, or otherwise secured be upset, in place under said top. The latch 10'isfree to turn on the pivot 11 over the lug 19 and the guard plate 9. v r

In the base .8 is an arcuate slot 20 struck from the center of the pivot 11. The slot 20 extends from a point adjacent to the back side of the space within the base 8 beyond or forward of a vertical plane which; extends lon 'itudinall of said base through the axis of tae ivot 11.

is a perforated lug 22. The lug 22 is on the tends transversely of the base 12 and wthrough the center of the pivot 11, to that where. the slot 20 is located. The slot 20 so located that its end, which is adj acent to the back side of thespace i i-the base 8, is approximately fin the aforesaid transverse 23 has one terminal at A. pin. 21 extends "downwardly fromthe latch 10 into and through the slot Depending from the top of the base 8 inside- ,tached to the lug 22 and the other terminal at tached to the pin 21.

-Normally the spring 23 retains the pin 21 in the outer or rear end of the slot 20 and against the back side of the base 8, and thereby d1sposes the la-tch 1O transversely of said base, as in Figs; 3 and'7, When the-latch 10 is swun on the aivot .11 a ainst the re 10 n s b V sinency oi the spring 23, to locate the pm 21 in the inneror forwardend of the slot20,

at which time saidlatch is isposed lengthwise of the base 8 and substantially as in Fig.- '1, said spring at the pin end is moved forward of the axial center of said pivot,

and "thus retains said latch in the aforesaid pos tion. As soon as the latch 10 s moved to carry the spr1ng23 rearwardly'o-f the axial center of the pivot 11, said spring acts to.

- The guard plate 9 has a transverse; slot 25 therein tO I'ECQlVG the lug 19-, and also. a cam slot"26 through whiclithe pin 21 extends before it passes into and through the slot 20. The cam slot 26is above the slot 20 and opens at its outer end'into" the outer or'rear part, on one si dc, of the slot 25. j i 1 WVhen the latch 10 is in its inoperative position, with thepin 21 in the inner end of l the slot 20, said pin is in-contact with the inner end of thecam slot'26. and retains theguard plate: 9 with its rear edge flush with the rear edgeof the base'8, but, when said latch is swung into operative position, said pin travels rearwardly 1n sa1d two slots, and,

. owing to theshape of said'camf slot, actuates said plate rearwardly. with said rear edge thereof pro ect1ng some distance beyond said rear edge of said base and ontothe frontedge portion of the base 12. There is a central recess 27 in the rear edge of the guard plate 9 to receive the post 13 when said plate is advanced, hence it is the parts,

of said plate at both ends ofsaid recess that project beyond the, base 8' and onto the top of the base 12. ThereCess 27 is. long enough to enable the base plate to clear the post a head 16. I

Normally the plate 9 is. in advanced position, but said plate is retracted and held in retracted position whenthe latch 10 is. actu-1.

ated into the position shown in Fig; 1 where said latch is 1161a by the. spring 23. Then the plate 9 is, of course, out ofthe path of any horizontal parting-rails in the upper sash, asis also the hook 17. The plate v9 is retracted by the pin 21 when the latter moves.

forwardly or inwardly. in the slot 20 and the cam slot 26.- Theslot 25. is of-sulficient length to permit to take place the necessary movement of the plate 9. The lug 19, the

two opposite sides of. which are in contact lit wit-hfthe. two longitudinal sides ofthe slot 25;, prevents the plate 9 from moving otherwise than in; a straight line forward'an'd backward;

The. pin 21, when in iits most forward or outer ,positiomicontacts with the backside of'the base 8,and, by reason of such contact, relieves the pivot-11 of much of the strain "it otherwise would'have to sustain from the latch-1O inthe forcible engaging'of the samewith or by the post 13, and whilesaidfilatch is in engagement with said post and subjected to force exerted thereon by attempted vertical movement bf either sash. This is an ..important feature, because otherwise. the

pivot 11 might in time become loose and even detached. V

The shape, size, and relative proportions of the post 13 and the lock 17 are such that,

when said hook, while disposed crosswise of the base 8, is thrust down onto said post,

as in lowering the lower window, or said post is thrust up against said jaw, as in raising the upper window, the hook is first forced aside, against the resiliency of the spring 23, and then, by the time the meeting-rails 1 and 2 areeven with each other,

said hook is actuated by said spring into engagement with said post beneath its head 16, and neither window can be moved to open it. Neither window can be opened because the pivot 11 holds the latch 10 to the base 8 on the meeting-rail 1, and the engagement between the post 13 and said latch causes the latter to be held securely in the base 12 on the meeting rail 2, or actually in contact with the friction plate 14see Fig. 2.

Hit be necessary or'desirable to draw the meeting-rails 1 and 2 closer together, pressure is applied to theihandle 24 in the direction to force thehook 17 farther into engagement with the post 13,.between the friction plate lt and the under-cut part of said post,

as clearly shown in Figs. 3 and 4. The plate 2 14 holds the hook 17 tightly in position so that thereis no danger of the same becoming accidentally disengaged.

In either of the above examples, upon grasping the handle 24 and forcibly swinging the latch 10, against the resiliency of the spring 23, inthe direction to disengage its hook from the post, and finally toassume the unlocked or unlatched position illus- To unfasten the windows, the. handle 24 is actuated in the direction to swing the hook 17 out. of engagement with the post 13, and into completely. retracted position, and retract'the guard plate 9, leaving the parts and members disposedas in the first View: Either or" both window'sfcannow be opened;

To fasten the :windowsv when closed,"v the latch 10 is moved far enough, from the Fig. 1

position, to carr springag backaopf h dead" center, and enable said spring to swing the-jaw 17 snaps into-engagement with the post.13.. At this time the guard plate 9 is advanced over the front-edge portion of the base 12'. The'spring 23 does notcause-the hook'17 to be drawn into full or complete engagement with the post. .13,'because of the presence of the friction plate 14,- but such. full and complete engagement is readily brought about upon grasping the handle-24 and forcingthe same to .the' leftl I we ,Morejor less change'in the shape, size, coir, struction, and arrangement,1o fsome or allof .said.latch crosswise of the base 8, and the; I lower window is pushed down or the upper W ndow raised, as the case may. be, until the parts of this fastener, may be made without departing from the spirit of our 'invention or' exceedingthe scope of'what claimed.
